You are incorrect, birthrates in Norway are on the high end in an European context. But since no European nation has a birthrate at or above replacement rate (2.2 children per woman if I recall correctly) you’d be right to say that there aren’t many young Norwegians, though there aren’t that many young Europeans in general. These trends can typically be generalized fairly well to most ‘highly developed’ economies, the same holds true for North America. But you’re probably right; not enough immigrants for Norwegian women to get impregnated by.
